Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A memory leak exists in the octep device setup() function within the Linux kernel. Specifically, if octep ctrl net init() fails, the function returns without releasing allocated memory and unmapping resources. The fix involves jumping to a cleanup label, unsupported dev, to ensure proper resource deallocation, aligning error handling with other function paths. The issue was identified through static analysis and code review.
